I'm pretty sure you have a typo in your definition of

. Taking what you wrote literally,

is a Boolean function that is always false.

Since

is always positive,

must always be negative, and

is an unwaveringly false statement since 3 is a positive number.

Such a function does not have a value that exists in

, hence there is no point in

to which

maps. Therefore there is no point of intersection between

and

.
